Many tries. Many half-fails. All of the package managers that I'm using (apt-get, synaptic) always cannot really finish installations or removals. Just minutes ago I was trying to purge the code::blocks package and IDE, the process didn't complete with multiple dependency errors:
Stuff about missing JDK and JRE
DPKG errors
And yet, I am completely certain that I have not deleted any of these packages, though I have a right to think again, because these problems seem to have started when I ran sudo apt-get autoremove.
Here is the complete output of my failed purging of code::blocks:
pi@raspberrypi:~ $ sudo apt-get purge codeblocks
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
codeblocks-common libcodeblocks0 libwxgtk3.0-0v5
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
codeblocks*
0 upgraded, 0 newly installed, 1 to remove and 1 not upgraded.
12 not fully installed or removed.
After this operation, 6,402 kB disk space will be freed.

So what exactly am I supposed to do to fix these problems? I have tried running sudo apt-get install default-jdk but apt-get said that the package didn't exist.
How do I fix these dependencies then?
How do you "configure" the packages?
Thank you.
